Basic tips I follow when doing my own oil changes -
** Make sure the hand or foot brake is on. If car is auto, put selector in park, for manual leave in 1st gear
** Place brick behind either rear wheel
** Change oil when the engine is warm, wear disposable gloves so you don't get burned or get your hands covered in used oil, keep rags or paper towels close by in case of mess
** Remove the oil cap and dipstick when draining oil to drain oil trapped by engine vacuum
